我们开始利用先进的数值模拟技术，开发一种可预测RMWR堆芯热水力性能的技术。作为这项技术发展的一部分，我们正在开发先进的界面跟踪方法，以提高流体体积守恒。本文介绍了采用先进的界面跟踪方法开发两相流仿真程序TPFIT的部分内容。给出了大尺度水蒸气两相流动的数值计算结果，并与实验结果进行了比较。在数值模拟结果中，预测的水平面空隙率分布趋势与先进中子射线照相技术的实测值一致，包括液体在相邻燃料棒位置的桥状形成，其中间隔最窄。
We start to develop a predictable technology for thermal-hydraulic performance of the RMWR core using an advanced numerical simulation technology. As a part of this technology development, we are developing the advanced interface tracking method to improve the conservation of volume of fluid. The present paper describes a part of the development of the twophase flow simulation code TPFIT with the advanced interface tracking method. The numerical results applied to large-scale water-vapor two-phase flow in tight lattice rod bundles are shown and compared with experimental results. In the results of numerical simulation, a tendency of the predicted void fraction distribution in horizontal plane agreed with the measured values obtained by the advanced neutron radiography technique including the bridge formation of the liquid at the position of adjacent fuel rods where an interval is the narrowest.
